Apple and its cofounder Steve Jobs certainly helped design and popularize storage devices throughout computing history. For example, the Mac mainstreamed Sony’s 3.5-inch floppy drive in the 1980s, but Apple was working on its own storage devices even before the Mac debuted. One ofour buddiesdiscovered this eBay listing advertising for what appears to be a prototype of a previously unknown NISHA hard drive adorned with the colorful Apple logo. It comes in a translucent case, and it could easily be the first Apple product we have seen like this, even though it never shipped. It is neither a Hard Disk 20 drive Apple introduced on Sept. 17, 1985 specifically for use with the Macintosh 512K nor is it a Hard Disk 20SC.

The latter product was the first SCSI drive Apple manufactured and deployed on the Macintosh Plus in 1986, effectively obsolescing the Hard Disk 20 unit. It is a safe bet that this unit represents an early prototype of one of Apple’s hard drives, but it could also be a new hard drive design that never saw the light of day. The seller could not tell either, as the drive did not power up. Eagle-eyed readers are aware that Apple of the past had been designing its own storage devices and the aforementioned Hard Disk 20 serves as an illustrious example of the company’s closed approach to hard drives.
